drm/xe/rtp: Ensure gt_was doesn't evaluate rules with engine types

2026-06-02T21:30:29Z

It is currently possible for a RTP rule, and subsequently a workaround, to expect contexts that may not be present when the workaround is applied. For example, the workarounds in the engine_was[] in drm/xe/xe_wa.c expect an engine entity to be active. Conversely, the gt_was[] is not depending on an engine entity to implement its workarounds. This kunit test addition checks the gt_was[] workaround list for any workarounds with XEP_RTP_ENGINE_CLASS() rules. If a workaround does have one of these rules, the workaround is then checked for the "FOREACH_ENGINE" flag, which ensures the workaround is implemented properly. The result of this test is an expectation failure if a workaround has an improper XE_RTP_ENGINE_CLASS() rule setup, and aims to prevent future issues of gt_was workarounds being applied without proper contexts. The gt_tunings[] RTP table has the same functional layout and requirements as gt_was[], so it shares the same kunit test function, minimizing excessive code. v6: - No change v5: - Remove unnecessary headers from xe_rtp_table_test.c v4: - No change v3: - Removed "VISIBLE_IF_KUNIT" keyword from xe_wa.h - Added gt_tunings[] for testing - Reworked KUNIT_EXPECT_TRUE() for easier parsing of errors v2: - Moved contents of xe_rtp_tables_test.h to .c and removed file - Renamed macro RTP_KUNIT_ARRAY_PARAM to RTP_TABLE_PARAM - Removed unnecessary functions and iterative components from generated _gen_params functions and implemented usage of table name and WA number as entry name - Condensed xe_rtp_table_gt_test() to use KUNIT_EXPECT_TRUE with no message statement - Removed xe_rtp_table_test_init() and xe_rtp_table_test_exit() as fake device initialization is not necessary Reviewed-by: Gustavo Sousa Signed-off-by: Violet Monti Link: https://patch.msgid.link/20260601200947.2032784-8-violet.monti@intel.com Signed-off-by: Matt Roper

drm/xe/kunit: Simplify xe_mocs live tests code layout

2024-07-12T08:49:51Z

The test case logic is implemented by the functions compiled as part of the core Xe driver module and then exported to build and register the test suite in the live test module. But we don't need to export individual test case functions, we may just export the entire test suite. And we don't need to register this test suite in a separate file, it can be done in the main file of the live test module.

As was done for the normal kunit tests, group the live tests into a single module, xe_live_test.ko. Reviewed-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20240312145158.2295351-1-lucas.demarchi@intel.com Signed-off-by: Lucas De Marchi

drm/xe: Group normal kunit tests in a single module

2024-01-16T17:53:27Z

Creating one module for each compilation unit to be tested seems excessive as the number of tests increase. Group them all in a single kunit test module called xe_test.ko. The tests requiring the physical device, aka "live" tests, are still kept in separate modules since they are normally triggered via igt, and not via kunit.py. After igt is converted, those can be merged in a single module as well.

drm/xe: Add KUnit test for xe_pci.c IP engine lists

2023-12-19T23:31:40Z

Add a simple KUnit test to ensure that the hardware engine lists for GMD_ID IP definitions are sensible (i.e., no graphics engines defined for the media IP and vice versa). Only the IP descriptors for GMD_ID platforms are checked for now. Presumably the engine lists on older pre-GMD_ID platforms shouldn't be changing. We can extend the KUnit testing in the future if we decide we want to check those as well. v2: - Add missing 'const' in xe_call_for_each_media_ip to avoid compiler warning.
